Taxonomy [top]

Kingdom Phylum Class Order Family
ANIMALIA CHORDATA AMPHIBIA ANURA HYLIDAE

Scientific Name: Hyla avivoca
Species Authority: Viosca, 1928
Common Name/s:
English Bird-voiced Treefrog

Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2004
Date Assessed: 2004-04-30
Assessor/s: Geoffrey Hammerson
Reviewer/s: Global Amphibian Assessment Coordinating Team (Simon Stuart, Janice Chanson, Neil Cox and Bruce Young)
Justification:
Listed as Least Concern in view of its wide distribution, presumed large population, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category.

Population [top]

Population: This species is widespread and common in the appropriate habitat. Most state herpetology accounts mention the existence of large populations. In South Carolina, Gibbons and Semlitsch (1991) noted "large choruses" in three locations on the Savannah River Site, plus additional smaller populations. Bartlett and Bartlett (1999) rated this species as common to abundant in Florida. Barbour (1971) noted the occurrence of a "magnificent population" in some of the swamps in Hickman County, Kentucky. Redmond and Scott (1996) stated that this species is especially abundant around Reelfoot Lake in Tennessee. "Locally common in some good habitats" in the limited range in extreme southern Illinois (Phillips et al. 1999). Abundant in floodplain swamps in western Union and Alexander counties, Illinois (Smith 1961:87). Apparently stable; no evidence of a decline in recent decades.
Population Trend: Stable

Habitat and Ecology [top]

Habitat and Ecology: Its habitat is permanent wooded swamps (tupelo, cypress, birch, buttonbush, and vine tangles) bordering rivers and streams. It may climb high into trees and is generally intolerant of impoundments that flood habitat. Males call from trees, shrubs, and vines that are in or next to water. Eggs and larvae develop in swamp pools.
Systems: Terrestrial; Freshwater

Threats [top]

Major Threat(s): Swampy habitat protects the species from many threats deriving from habitat alteration, but threats include clearing and draining of baldcypress-tupelo swamps (Phillips et al. 1999).

Conservation Actions [top]

Conservation Actions: Occurs in several protected areas.
